Hi All,
I have a question about managing subdirectories with
autoconf/automake.
Our project contains several independent packages. For
each package we have a subdirectory and each subdirectory
has a configure script.
From the top level configure script the user should choose
wether s/he wants to compile a specific package or not.
e.g.: ./configure --enable-gui
By now (and that solution works with autoconf-2.53 and automake-1.6.3)
we use the AC_CONFIG_SUBDIRS macro in the top level configure.in
file:
if test "x$gui" = xtrue; then
AC_CONFIG_SUBDIRS(Utilities GUI)
else
if test "x$model" = xtrue; then
AC_CONFIG_SUBDIRS(Model)
else
AC_CONFIG_SUBDIRS(Utilities GUI Model)
fi
fi
Trying the same code with autoconf-2.57 and automake-1.7.7 results in the
following error when running automake:
configure.in:29: error: `Utilities' is already registered with
AC_CONFIG_SUBDIRS.
/usr/local/src/autoconf/autoconf-2.57/lib/autoconf/status.m4:1073:
AC_CONFIG_SUBDIRS is expanded from...
configure.in:29: the top level
Is there a better/standard solution for our purpose ?
With regards
Kai
